HaloTag® Protein Purification System

The HaloTag® Protein Purification System is designed to purify proteins fused to the HaloTag® novel protein tag that enhances the expression and solubility of recombinant proteins. HaloTag® Technology enables the covalent, efficient and specific capture of a protein of interest onto HaloLink™ Resin, thus overcoming the equilibrium-based limitations associated with affinity tags (i.e., poor capture of proteins expressed at low levels and protein loss during washing of the purification resin.

The HaloTag® technology offers a quick and convenient way to test protein expression of HaloTag® fusio...

The HaloTag® Protein Purification System is designed to purify proteins fused to the HaloTag® novel protein tag that enhances the expression and solubility of recombinant proteins. HaloTag® Technology enables the covalent, efficient and specific capture of a protein of interest onto HaloLink™ Resin, thus overcoming the equilibrium-based limitations associated with affinity tags (i.e., poor capture of proteins expressed at low levels and protein loss during washing of the purification resin.

The HaloTag® technology offers a quick and convenient way to test protein expression of HaloTag® fusion proteins as well as monitor the efficiency of immobilization to HaloLink™ Resin by labeling with fluorescent HaloTag® TMR Ligand followed by SDS-PAGE analysis. Guidelines can be found in the HaloLink™ Resin Technical Manual#TM250, the HaloLink™ Protein Array Technical Manual#TM310 and the HaloCHIP™ System Technical Manual#TM075.

Outline of Procedure
The HaloTag® protein, a 34kDa mutated hydrolase, covalently attaches to HaloLink™ Resin via an immobilized chloroalkane ligand. TEV Protease cleaves the target protein from the HaloLink™ Resin. The TEV Protease, which has an N-terminal (HQ) tag, is removed from the protein of interest using HisLink™ Resin, and the purified protein of interest is recovered. The appropriate vector that encodes the HaloTag® protein and expresses protein optimally in E. coli is pFN18A HaloTag® T7 Flexi® Vector (G2751) or pFN18K HaloTag® T7 Flexi® Vector (G2681). These vectors can be purchased separately.
